Alpha

A predetermined threshold in hypothesis testing that defines the probability of making a Type I Error, usually set at 0.05, indicating a 5% risk of false positive.

Null Hypothesis

A hypothesis that suggests there is no significant difference or effect, serving as a default position until evidence suggests otherwise.

Statistical Significance
